Bang! One split second passed and there came a terrific explosion. The sub had blown up.

By this time the enemy’s plan was plain to see. This sub had been sent in to wreck the ship’s radio at once, then to sink her at their leisure. It would be impossible this way for the carrier to summon aid from land planes. It was true that this task might have been taken over by a cargo ship or a destroyer but before these ships could know of the need, it would be too late.

With the threat to his ship removed, the Captain ordered his planes off on a search for the remainder of the wolf-pack.

With a strange feeling at the pit of her stomach, Sally heard them take off one after the other.

“Fred and all his comrades,” she whispered. “What will the score be now?”

A youthful face appeared at the door. “I’m Second Lieutenant Burns,” said the boy. “I was sent to pinch-hit on the radio.”

“That’s fine!” Sally gave him her best smile. “You just look things over. If you want to give me a few moments off, it will be a blessing straight from Heaven.”

“Things happen pretty fast.” He smiled back at her.

“Too fast.” She was rocking a little on her feet.

“You were lucky at that.” He grinned. “I watched those shots. If it hadn’t been for that singing gun crew, one of those shells would have blown this cabin sky high.”
